What this agent does

Answers the question, not the account change

In

  1. 01

    Ingest the contact, the account record and your authentication policy from supported care, billing or CRM sources.

  2. 02

    Normalise plan names, charges and device details, and carry each answer forward with the record it came from.

Reason

  1. 03

    State that the customer is speaking to an AI system, and keep a human adviser one request away.

  2. 04

    Run the authentication challenge your policy configures — never a name, date of birth, address or last four.

  3. 05

    Answer account, service and billing questions from the documented record, and name the record behind each answer.

Decide

  1. 06

    Withhold call detail until a 47 CFR 64.2010 path clears, and offer the address or number of record instead.

  2. 07

    Hold chargeable adds, removals and changes for a named adviser, with the recurring price and term stated back.

Out

  1. 08

    Retain the contact, the authentication run, the record answered from and the adviser's disposition.

  2. 09

    Execute write actions only inside the approval boundaries agreed during implementation.

Product statement

The agent answers and gathers; a named adviser decides anything chargeable or CPNI-bearing, and the carrier stays the regulated entity under § 222.

Example workflow

One contact, question to answer

  1. 1Contact receivedVoice line, chat, app message, relay call or an inbound email
  2. 2Context assembledPlan, device, charges, prior contacts and any recorded accessibility need, each with its source
  3. 3Answer proposedAnswer, the record behind it and confidence
  4. 4Controls appliedAuthentication tier, call-detail withholding, chargeable-change holds and confidence threshold

No human action required

Stages 1 to 4 run unaided, and nothing chargeable moves at any of them — the agent is answering, and the adviser's lane opens at the confidence gate.

5DecisionBranches at the confidence threshold
High confidence

Goes to the named adviser to release.

Low confidence

Adds a supervisor read first.

Adviser review

The answer is held with its record, its authentication trail and the confidence.

Release · Correct · Send to supervisor review

Released — the customer is answered

  1. 6Care and billing systems updatedOnly where write access and approval policy allow it
  2. 7Outcome evaluatedRepeat contacts, corrections in review, complaints logged and failed authentication attempts

Corrections

Each adviser correction is counted in the evaluation.

What should not run autonomously

Human approval stays in control

Outside the boundary — human approval required

8 items

  • Releasing call detail on an unverified contact.
    • Adding, removing or changing a chargeable feature.
    • Anything touching a suspected or reported breach.
    • Closing a contact that carries a relay or access need.

  • Automation boundary

    Agent acts unaided

    • ✓Answer account and billing questions from the documented record.
    • ✓Gather the contact, the account and the prior contacts.
    • ✓Run the authentication challenge the policy configures.
    • ✓Hold anything chargeable or CPNI-bearing for a named adviser.

    Any write happens inside the boundaries agreed at implementation, never ahead of the adviser's release.

    • Effecting a SIM change, port-out or number transfer.
    • Disconnecting a line or cancelling a subscription.
    • Placing outbound marketing calls, texts or AI voice.
  • Changes to authentication or escalation thresholds.

As received

Taken from the rated bill and the account record — nothing on this side is written by the agent.

Records used

  • Rated usage on the bill
  • Plan and bundle on file
  • Prior contacts on the account

Why this answer

It reads back a charge already on the bill, and releases no call detail.

What the score decides

Below the configured threshold the answer picks up a supervisor read before it is sent.

Value

Where AI adds value

The same four claims, placed at the point in the workflow where each one applies.

Where the value lands

Value 01 – 04

Every contact

From the account record

03Answering

Answer from the record

Draw on the rated bill, the plan on file and the authentication tier your policy sets for that data.

01Approved path

Answer without the hold

Documented account and billing questions come back answered, on the channel the customer used, relay included.

02Human review

Send advisers to the held work

Chargeable changes, call-detail requests, breach signals and low-confidence answers are marked, so adviser time lands where being wrong is costly.

04

Build an evidence trail

The question, the record it was answered from and the adviser who took it stay on the case.

Integrations

Typical integrations

Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

Agent controls

Six layers between the model and the customer

Each control wraps the one inside it. What a layer does not catch is named in the map below it.

How Nestack evaluates it

Evaluate the whole contact path — not only the answer the customer hears.

Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Surface — the answer the customer acts on

  1. E1Final-output evaluationDid the answer match the record it was drawn from?
  2. E2Step-level evaluationDid the agent use the right account, tariff and authentication configuration?
  3. E3Tool evaluationDid it read the correct account and write to the correct case?
  4. E4Confidence calibrationDo low-confidence answers actually attract more adviser corrections?
  5. E5Slice evaluationHow far apart do correction rates sit across specific contact reasons?
  6. E6Business outcomeHow many contacts came back a second time, and how many closed without reaching an adviser who should have seen them?

Failure modes

Where each failure originates in the agent

Seven ways a contact goes wrong, placed at its stage.

Agent lifecycle

Direction of processing →

  1. 01 · Retrieval

    1 mode

    • NF-03

      Superseded record read

      The answer comes from a tariff the account has since moved off.

    Stage gathers

    Contact, account record, rated bill and prior contacts

  2. 02 · Reasoning

    2 modes

    • NF-04

      Biographical authentication

      Identity is treated as settled on name, address or last four.

    • NF-06

      Chargeable change inferred

      A conversational cue is read as authorisation for a charge.

    Stage proposes

    The answer, its record and the confidence

  3. 03 · Tool / write

    2 modes

    • NF-02

      Call detail read back

      Usage or call detail leaves the session without a cleared path.

    • NF-05

      Relay turn read as silence

      A relay operator's typing delay ends the contact early.

    Stage writes

    Only where write access and approval policy allow it

  4. 04 · Output

    1 mode

    • NF-01

      Answer contradicts the bill

      The agent states a charge or entitlement the record does not show.

    Stage returns

    The answer the customer acts on and the case

  5. 05 · Change / Version

    1 mode

    • NF-07

      Silent disclosure regression

      A model or rule change widens what the agent will read back.

    Stage tracks

    Model, prompt, authentication and disclosure rules

  • Sev-1 · answers outside the boundary
  • Sev-2 · a wrong answer reaches the customer
  • Sev-3 · records degrade, contact goes to review

Affected slices

Overall answer quality can hide one contact reason

The slice a total buries here is call-detail and usage requests: few contacts, most of the corrections. Nestack reports the correction rate by contact reason, not only in total.

Evidence-linked improvement

The loop ends in a regression case

A cycle closes when the failure is a regression case the next release has to pass. That suite is what the next contact into care is measured against.

Improvement cycle · five stages

Switchback — the path turns at Improve and returns at Learn

  1. 01

    Detect

    Adviser corrections rise in one contact reason.

  2. 02

    Diagnose

    The case record is the unit of diagnosis — the question, the authentication run against it, the record answered from and who took it over.

  3. 03

    Improve

    The change ships against a version, with the contacts that exposed it attached.

  4. 04

    Verify

    Release is blocked until the affected regression cases pass again.

  5. 05

    Learn

    The case joins the permanent suite and the care playbook.

  6. Learn → Detect

    The return edge. Detection starts again against a suite one case longer.
